This algorithm uses either the Debye or Einstein method to calculate kinetic energy and root mean squared momentum and in the Debye case, root mean squared displacement, from a given temperature and atomic mass. The outputs from this can be used to help predict the nature of peaks in Vesuvio data.
Example - VesuvioPeakPrediction
vesuvio_debye_params = VesuvioPeakPrediction(Model='Debye', Temperature=[300], AtomicMass=63.5, Frequency=20, DebyeTemperature=347)
vesuvio_einstein_params= VesuvioPeakPrediction(Model='Einstein', Temperature=[300], AtomicMass=63.5, Frequency=20, DebyeTemperature=347)
vp = vesuvio_debye_params
print('--------Debye--------')
for c in vp.keys():
print('%s: %.4f' %(c, vp.column(c)[0]))
vp = vesuvio_einstein_params
print('\n--------Einstein--------')
for c in vp.keys():
print('%s: %.4f' %(c, vp.column(c)[0]))
